Improvement in plows



UNITED STATES ISAAC M. FORD, OF BELTON, TEXAS.

IMPROVEMENT IN FLOWS.

Specification forming partof Letters Patent No. 146,815, dated January 27, 1874; application filed December 1, 1873.

To all whom 'it may concern:

Beit known that I, ISAAC M. FORD, of Belton, in the county of Bell and State of Texas, have invented a new and useful Improvement n1 Plows, of which the following is a specification:

Figure I is a side view of my improved plowplate, shown as applied to a standard and beam. Fig. 2 is a perspective view of the same; and Fig. 3 is a diagram illustrating the inode of laying out the plate.

My invention has for its Object to furnish an improved plow, which shall be so constructed that it will scour and keep bright in the stiifest and most sticky prairie-soil, and will thus work without clogging where ordinary plows cannot work. The invention consists in an improved plowLplate, formed of a single piece of iron or steel, with its point in the form of an isoseeles triangle with a rearwardly-inclined land-side iian ge, with the anguiar line between the land-side flange and the mold-board concaved upon the arc of a circle about six feet in diameter, and with the moldboard convexed, so that a line drawn from its rear corner to the point of intersection of the said angular line and the point may be upon the arcor' a circle of about twelve feet in diameter, as hereinafter fully described.

A represents the plow-beam, to the rear part of which the upper end of the standard B is attached. The forward side of the standard B is concaved to form a seat for the plow-plate 'upon the arc of a circle of six feet in diameter. C D E is the plow-plate, which is made of a single piece of iron or steel, and formed in the manner hereinafter described, and struck or pressed into the desired form. O is the point, which is laid out in the form of an isosccles triangle, c b c, the base a c of the triangle forming the land side of the point, and one of the equal sides a b forming the moldboard side of the point, as shown in Fig. 3. D is the ilangc or land-side of the plate, which is made about two inches wide, and is bent or inclined to the rearward, as shown in Fig. 2, so that dirt, weeds, or trash will slide Off and not clog the plow. The land-side corner c of the point C projects about two inches beyond the edge g 71, of the flange D. The plate so formed is bent into such a shape that the angular forward edge of the plow along the line df may beconcaved upon the arc of a circle of about six feet in diameter, and the moldboard E may be convened, so that the line d c may be upon the arc of a circle of about twelve feet diameter.

With this constrnction,tl1e plow-plate will .i

scour smooth, and the most sticky soil will not adhere to it.

Having thus described my invention, I claim as new and desire to secure by Letters Iatent- An improved plow-plate formed of a single piece of iron or steel, with its point C formed at irregular angles, as shown, and with a rearwardly-inclined land-side ilange, D, extending from the angular line fd, the latter being concaved upon the arc of a circle, as set forth, and the mold-board E, from its rearward cor- 'ner e to the point at d, being convexed, as

specified, all constructed and arranged substantially as herein shown and (fie-scribed.`
